Questions
How big is the Unisense PCB?
It measures 58.5 × 85 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Unisense use?
121 parts, built around the SP3485EN-L/TR, RS485, BME280 and VEML6040A3OG. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Unisense KiCad files?
From the mburger82/unisense repository on GitHub, at the commit this page was made from: the board is HW_Unisense/Unisense.kicad_pcb and its schematic HW_Unisense/Unisense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Unisense design in my own project?
Its repository states no licence, so its author keeps all rights: ask mburger82 before reusing the design.
